INDIANAPOLIS — Former NFL veterans Greg Hardy, Brandon Browner and Kellen Winslow Jr. are among the initial commitments to an independent developmental league scheduled to debut next month, according to the league’s founder.

The Spring League will open practice April 5 with four teams. They will play a total of six games between April 15-26, all at the Greenbrier Resort in White Sulphur Springs, West Virginia. Rosters will be filled by players not currently with an NFL team.

The league is not affiliated with the NFL, but NFL officials informed teams last December of the Spring League’s plans detailing a structure for scouting and signing players later in the offseason.

Spring League CEO Brian Woods is attending the NFL scouting combine this week, meeting with team executives and agents to provide details on the operation. Woods was previously the commissioner of the Fall Experimental Football League, which staged games in 2014 and 2015.

Other notable players who have committed to the league include receiver David Nelson, running back Ben Tate, receiver Jalen Saunders and quarterback Ricky Stanzi. Players will receive room and board at the Greenbrier, but will not be paid game salaries.

INDIANAPOLIS — Often a prospect at the NFL’s scouting combine will step into the room the Denver Broncos use for player interviews and feel a bit in awe seeing John Elway for the first time.

For Stanford running back Christian McCaffrey, it was a far different experience. McCaffrey’s father Ed played for the Broncos’ back-to-back Super Bowl winners to close out the 1997 and 1998 seasons, so seeing Elway was a reminder of home.

It was the same when McCaffrey saw Oakland Raiders coach Jack Del Rio inside Lucas Oil Stadium. Del Rio’s son, Luke, was a quarterback for McCaffrey’s high school team when Jack Del Rio was the Broncos defensive coordinator.

“Looking at the Raiders’ side and the Broncos’ side, so many people here that I’ve grown up knowing,’’ McCaffrey said Thursday at the combine. “It’s pretty surreal now that I’m here.’’

McCaffrey met with the Broncos’ decision-makers Wednesday night. Not as a hometown kid catching up, but as a versatile runner, receiver and returner the Broncos could use to spice up an offense that will get plenty of attention in free agency and the draft.

Or as McCaffrey put it: “I believe I would be an every-down back and a specialist.’’

“He’s a dynamic player who can do it all,’’ Elway said. “Wherever he goes he’s going to have an immediate impact.’’

Asked if it would be any more difficult for McCaffrey to play for the team his dad played for, in the city where his parents still live — Ed is a cohost on an afternoon radio show in Denver — Elway said Christian’s competitiveness would make it an easy transition.

“Knowing what I know of Christian and knowing how competitive he is, he’s got a great deal of respect for his dad, but he also looks at himself and he’s going to blaze his own trail,’’ Elway said. “The expectations that he has for himself are awful high.’’

The Broncos have the 20th pick in the first round and, depending on the team or the draft analyst polled, McCaffrey sits as the No. 3 or No. 4 back on the draft board leading up to the combine workouts for backs Friday.

It is a deep draft class at the position as well, which could make teams more patient in selecting one and potentially push a back or two further down the board than one might expect. But LSU’s Leonard Fournette, Florida State’s Dalvin Cook, McCaffrey and Tennessee’s Alvin Kamara generally are regarded as the top of the class.

INDIANAPOLIS – Don’t count on B.J. Raji to help bolster the Green Bay Packers’ defense.

The former Pro Bowl defensive tackle has not shown any interest in returning to the NFL one year after he decided to take what he called a “hiatus” from the game at age 29.

“When he made the decision it was to go home and take care of his family and be with them, and he’s still doing that,” Raji’s agent, Brian Murphy, told ESPN.com Thursday at the NFL scouting combine. “His family is his first priority. He hasn’t really thought about football.”

It was at the combine last year that Murphy and fellow agent Camron Hahn were putting the finishing touches on a deal for Raji to re-sign with the Packers.

ALAMEDA, Calif. – Derek Carr’s initial plan was to ramp up his rehab from his broken right fibula in time to play in the Super Bowl, had the Oakland Raiders advanced that far in the NFL’s postseason tournament.

But when the Raiders fell at the Houston Texans in the opening weekend of the playoffs, Carr’s comeback took a more timely approach, though Raiders coach Jack Del Rio said at the NFL combine in Indianapolis on Thursday that his quarterback was on track for next season.

“He’s doing well,” Del Rio told ESPN’s Matt Barrie. “Yeah, Derek is healing, and we’re happy about that. He’s obviously a very vital piece of what we do and … we’re happy about the way things are coming along.”

Del Rio was asked how Carr’s ascent played a part in the Raiders’ revival, from an 0-10 start in 2014 to starting out 12-3 in 2016.

“Well, it’s been tremendous for us,” Del Rio said. “I think finding that trigger man is so huge for you and one of the things that we’ve done is we’ve played to the talent that he does have. So some of the things that he did in college, we’ve integrated into the offense and how we approach it.”

Carr, who finished tied for third in NFL MVP voting, passed for 3,937 yards while completing 63.8 percent of his passes in 15 games. He also had 28 touchdown passes and six interceptions for a passer rating of 96.7 with seven come-from-behind drives in the fourth quarter or overtime.

In an interview with Sirius XM this week, Carr said he looked forward to coming back with his “hair on fire” in Oakland.

“We’re really close,” Carr said. “It feels good, obviously, I still have a little bit of the process to go, so I won’t put a number on it … I’ll never put a number on it, but I can assure you I’ll be back 100 percent, ready to go, and we’re almost there.”

Carr also acknowledged after the season he had suffered a fracture in his right (passing) finger on a mistimed snap in Week 12. It was called a dislocation at the time.

With both the finger and leg, broken in Week 16, healing, Carr said he wants to participate in the Raiders offseason program, which begins April 17. Rookie minicamp is scheduled for May 5-7 with OTAs on May 23-25, May 30-June 1 and June 5-June 8 and mandatory minicamp June 13-15.

“My goal is to make sure there’s no lingering effects of anything,” Carr said. “Now it’s just going to be up to what the team and myself, getting together, what we think is the best plan. There’s nothing holding me back physically. We’re just trying to be smart in the way we do it. You don’t want anything to push it back a couple weeks just because maybe we rushed a certain thing.

“We’ve taken this process as slow as possible ever since our team got knocked out of the playoffs. We’re going to continue to do that, but I fully expect to be out there with my teammates when everything starts up.”
